嵌入

SVD is used to extract singular value which is embedded copyright protection into digital audio based on modular arithmetic.

将数字音频信号用奇异值分解所得的奇异值作为水印的嵌入系数，对该系数采取模2取余的方法作为水印嵌入策略。

In this algorithm, the product of two huge primes is the secret information, which is further converted into n natural numbers and then encoded into planted plane cubic tree structures which are embedded into the software codes as software watermark.

水印嵌入的入程是：首先将两个大质数的乘积采取中国剩余定理划分成n个天然数，然后再将这n个天然数编码入n个平面环路树PPCT构造中，将这些构造的构建代码嵌入软件代码中。

Together with some basic knowledge of Linear Algebra, we prove that there exists a polynomial time algorithm for finding the shortest contractible cycle in an locally LEW-embedded graph. 3. By some results of Minor Theorem, we prove the crossing numbers of some circular graphs C(10,4), C(9,3), C(8,3) on the projective plane.

利用C.Thomassen在大边宽嵌入方面的工作，得到了局部大边宽嵌入图的一些性质，再利用线性代数的知识，证明了在局部大边宽条件下存在多项式时间算法可以找到一个图的最短可收缩圈。

This implies the existence of a polynomially bounded algorithm to find a shortest contractible cycle, a shortest separating cycle, and shortest cycle in an embedded graph in the projective plane and answers the open problems raised by Mohar and Thomassen in the case of projective plane embedded graph.

另一方面，通过定义嵌入图的几何对偶图及其相应的嵌入系统，得到几何对偶图中的可分离圈就对应于原图中的割；反之，若几何对偶图中的割在原图中对应于一个圈，那么该圈一定可分离。

The embedding problem for resolvable designs is one of the important contents in design theory.

带有可分解性质设计的嵌入问题是设计理论嵌入中一项重要内容。

Using the information obtained from the study of these normal variations of vertices near a sharp edge or a high curvature area of the target space to detect features.The watermarks embedded by using the method can be detected,to some extent,after such attacks as cropping, simplification,similarity transformation,and additive random noise applied on the watermarked point set model.

最后对已加水印的点集模型应用不同的攻击，比如剪切、简化和附加随在特征点附近嵌入水印信息机噪声之后，结果显示通过这种方案嵌入的水印，在某种程度上仍可以被检测到。

Last, this paper introduced some concepts of multiscale geometrical analysis and curvelet transform theory. Because curvelet can showed this feature more 'sparsely' in the function included singular curve or singular side in two dimension space or multi-dimension space. This paper provided a robust digital watermarking technology algorithm based on curvelet transform. watermarking information was embedded into coarse scale coefficients after curvelet transforming, choose right embedding strength. Testing proved it has good invisibility and robustness.

最后，介绍了多尺度几何分析和曲波变换理论的相关概念，鉴于曲波能对二维乃至高维空间中含奇异曲线或者曲面的函数进行更"稀疏"地表示这一特性，本章提出了一种基于Curvelet变换的鲁棒数字图像水印算法，该算法将水印信息嵌入到经曲波变换后的图像的粗尺度系数中，合理选择的嵌入强度，试验表明该算法具有较好的隐蔽性和鲁棒性。

This is perfect for embedded systems, where each device is actually a different kind of special purpose hardware.

对于嵌入系统来说这是非常棒的，因为嵌入系统实际上就是一种特殊目的的硬件。

The experimental results show that the proposed method performs better than the fixed-length Least-Significant-Bits substitution method in DCT domain in terms of message capacity and image quality.

实验结果表明：该文方法在图像质量和信息嵌入量方面，都优于DCT域内固定嵌入位数的信息隐藏方法。

The selected image salient features are used to compute geometric transformation parameter of watermarked images. After recovering the size and aspect of watermarked images, the watermark detector is synchronized with embedded watermark. Thus the watermark detector can detect the watermark.

利用提取的图像固有特征点估计水印化图像几何变换参数，恢复经几何变换的水印化图像，同步水印检测器与图像中嵌入的水印信号，使水印检测有效检测嵌入的水印信号。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
